“…The directional aggregation of glycine cations at the charge collection interface and the accumulation of ethylenediammonium ions at the interface led to the formation of dipole interlayer, which effectively improved the device performance (Figure 10a-b). Choi et al [117] added different polar substances (BCP, QPPO and QDPPO) at the interface between the perovskite and ETL to control the interface dipoles, so that the interface dipoles are evenly distributed, effectively reducing charge recombination, and maintaining a high FF at low light intensity in the room. Song et al [118] used ethoxylated polyethyleneimine (PEIE) to modify the interface between SnO 2 and perovskite.…”

Interface modification and bulk doping are two major strategies to improve the photovoltaic performance of perovskite solar cells (PSCs). Dipolar molecules are highly favored due to their unique dipolarity. This review discusses the basic concepts and characteristics of dipoles. In addition, the role of dipoles in PSCs and the corresponding conventional characterization methods for dipoles are introduced. Then, we systematically summarize the latest progress in achieving efficient and stable PSCs in dipole materials at several key interfaces. Finally, we look forward to the future application directions of dipole molecules in PSCs, aiming at providing deep insight and inspiration for developing efficient and stable PSCs.

“…One of the first studies of PSCs under low irradiance conditions was performed by Raifuku et al They demonstrated that PSCs performed better at low irradiance than c-Si solar cells and also that there is room for the optimization of solar cells intended for low light operation. In the following years, research efforts on indoor specific PSCs accelerated, with research groups focusing on electron transport layer optimization and its interface to the perovskite layer, , deposition techniques and the composition of the perovskite layer to improve crystallization and reduce the number of surface and bulk defects, − the optimization of J–V hysteresis and consequent PCE improvement. , Skafi et al demonstrated flexible PSCs for indoor use, while Kin et al combined three PSCs connected in series with a sodium-ion battery to construct a very compact nonintermittent renewable power solution for small electronics devices.…”

Indoor photovoltaics (IPV) hold enormous market potential driven by the rising demand for perpetual energy sources to power various small electrical devices and especially Internet of things (IoT) devices. Perovskite solar cells (PSCs) offer exciting prospects for this role. This study sets out to deepen our knowledge of PSC performance under realistic indoor conditions. For this purpose, we designed an indoor monitoring system that maintains four solar cells at their maximum power points and simultaneously logs their performance and environmental conditions. Throughout a 12-month period, we monitored the behavior of three PSCs and one crystalline silicon solar cell (c-Si SC), all with an active area of approximately 1 cm 2 . Measured daily energy yields in conjunction with a comparative overview of minimum energy requirements of different wireless technologies indicate that a single 1 cm 2 PSC should be enough to power an IoT device with one of the available short-range, low-power wireless technologies on most days of the year, a fact confirmed by a prototype device. There are, however, a few days every year when the available energy would not be enough to even power the maximum power point tracking, highlighting the need for at least some energy storage capacity. Solar cell orientation dependence measurements demonstrated a 36% advantage for optimal orientation and a 72% performance drop for the worst orientation compared to horizontal orientation. A one-year energy yield results show a remarkable three-to-one advantage in favor of the best PSC (148.8 mWh/cm 2 ) over the c-Si SC (46.0 mWh/cm 2 ). The best of the three PSCs also retained most of its initial performance throughout the year with a simple edge-sealing encapsulation.
